Application of bio-catalyst (NOE-7F) in thermal treatment can adequately dispose dark-black fly ashes from co-combustion of both waste tires and coal. After thermal treatment of fly ashes by adding 10% NOE-7F, the carbon contents reduced by 37.6% and the weight losses increased by 405%, compared with the fly ashes without mixing with NOE-7F. The combustion behaviors of wasted tires combustion fly ashes with NOE-7F were also investigated by both thermogravimetric analysis (TGA) and differential thermal analysis (DTA). The results verify that NOE-7F has positive effects on the combustion of residual carbon and toxic polycyclic aromatic hydrocarbons (PAHs) enhance the energy release and reduce the toxicity during the process of thermal treatment. Furthermore, using NOE-7F to dispose high-carbon content fly ashes did improve the compressive strength of fly ashes and concrete mixtures. Therefore, NOE-7F is a promising additive which could decrease treatment cost of high-carbon content fly ashes and reduce the amount of survival toxic PAHs.
生物催化剂（NOE-7F）在热处置中的应用可以充分处理废轮胎和煤共燃烧产生的深黑色飞灰。通过在飞灰中添加 10%的 NOE-7F 进行热处置，与未混合 NOE-7F 的飞灰相比，碳含量降低了 37.6%，重量损失增加了 405%。还通过热重分析（TGA）和差示热分析（DTA）研究了废轮胎燃烧飞灰与 NOE-7F 的燃烧行为。结果表明，NOE-7F 对残余碳的燃烧有积极影响，有毒多环芳烃（PAHs）的释放也增强了热能释放，降低了热处置过程中的毒性。此外，使用 NOE-7F 处理高碳含量飞灰确实提高了飞灰和混凝土混合物的抗压强度。因此，NOE-7F 是一种很有前途的添加剂，可以降低高碳含量飞灰的处理成本，并减少存活有毒多环芳烃的数量。
